Power supply with management interface and method therefor

An information handling system comprising:

• a power supply (PSU) to provide power to the information handling system;
• and
• a baseboard management controller (BMC), the BMC communicatively coupled to the PSU by a first signal interconnect and a second signal interconnect, the BMC configured to receive, via the first signal interconnect, an alert from the PSU indicating that an operating parameter of the PSU exceeds a predetermined threshold,
• wherein the first signal interconnect is associated with a PWR_OK signal of an Advanced Technology eXtended (ATX) specification and the second signal interconnect is associated with a PS_ON# signal of the ATX specification.

A method comprising:

• receiving at a baseboard management controller (BMC), via a first signal interconnect communicatively coupling a power supply unit (PSU) to the BMC, an indication from the PSU that voltage levels provided by the PSU are valid;
• and
• receiving at the BMC, via the first signal interconnect, an alert from the PSU indicating that an operating parameter of the PSU exceeds a predetermined threshold,
• wherein the first signal interconnect is associated with a PWR_OK signal of an Advanced Technology eXtended (ATX) specification.
